c# - 如何从另一种形式启用一种形式的按钮？

Question

我正在制作一个迷宫，我希望在玩家完成第 1 级（在表单 1 中）时启用我的“第 2 级”按钮（在主表单中）。所以我该怎么做？

Answer 1

Create a new event on the LevelForm, such as:

public event Action LevelCompleted;

Fire that event when the level is completed:

//run this code as soon as you know the level is completed
if(LevelCompleted != null)
    LevelCompleted();

Then have the main form subscribe to that event and do...whatever, when the level is completed:

level1Form.LevelCompleted += () => level2Button.Enabled = true;
